Is it possible to get records between a Timespan from a DataTable using the RowFilter property of the Defaultview that belongs to the table.

Purpose:
I would like to check if Current Time(DateTime.Now.ToString()) falls withing the Time defined in the Database table schema. Schema of the table is defined below

`Name | From | To | JoinedOn |`

where From To are datetime columns on the database table. I would like to compare only time values from the datetime columns rather than the dates also. I Tried below but doesn't yield the result.
dt_Temp.DefaultView.RowFilter = "From < '"+ DateTime.Now.ToString()+"' AND To >'"+ DateTime.Now.ToString()+"'"; anyone have any idea?
